ETAP is software for modelling and analysing electrical power systems. Engineers use it to run load flow, short circuit, protection coordination and arc flash studies before a system is built or modified.
The main studies
- Load flow: confirms voltages and loading across the network.
- Short circuit: calculates fault currents so equipment ratings can be checked.
- Protection coordination: sets relays and breakers so the nearest device trips first.
- Arc flash: estimates incident energy for safety labelling.
Who needs it
Electrical design engineers on larger buildings, utilities and industrial plants, and anyone preparing or reviewing power system study reports. If your work stops at final circuits in small buildings, electrical design comes first.
What you need before starting
A working grasp of single line diagrams, per-unit calculations and protection basics. ETAP does the arithmetic, but you must judge whether the result is sensible.
How to learn it
ETAP training is most useful when you build a model from a real single line diagram and write up the results as a short report.

Frequently asked questions
Is ETAP hard to learn?
The interface is manageable. The engineering judgement behind the studies takes longer.
Is ETAP used in the UAE?
Yes. It is widely used by consultants, utilities and industrial clients in the region.
Should I learn ETAP or DIALux?
They do different jobs. ETAP analyses power systems; DIALux designs lighting.
